In fact, it started with Ohamoka, the commander of the 9th Division of the Grizzly Army mixed in Buffalo, ordered the bombardment of Barry St. Redegg who landed on the southern shore of Lake Ontario, and then on to the shore of the Fourth Division of the Grizzly Army stationed in Norfolk. The second battalion of the Anti-Cannon Regiment cleanly sank eight capital ships of the Guadeloupe Fleet of the Royal French Navy, and the situation of the entire War of Independence was quietly changed.

　　 Although France still declared war on Britain at the end of February 1778, the lack of eight capital ships of the Guadeloupe Fleet caused the uncertainty of the Atlantic situation to increase again. Even Spain, like the original time and space, declared war on Britain on June 16, 1779. The Netherlands also joined the United States, France and Spain to fight against Britain, but the main purpose of Spain’s declaration of war on the British was to lay down the fortress of Gibraltar. The fortress that had been absent from the Kingdom of Spain for eighty years returned to the Kingdom of Spain.

　　 Therefore, the navy of the Kingdom of Spain did not have much success in the Atlantic, and the French would have to rely on the French to contain the British navy in the Atlantic.

But the French navy alone could not suppress the British fleet, so the impact on the supply of British troops in North America was not as great as the original historical time and space. Therefore, Henry Clinton did not order the withdrawal of Philadelphia, and also Smoothly opened up the southern battlefield, and in the southern battlefield, repeated battles, fighting the Continental Army squirming around.

　　 If this situation continues to develop, the British are absolutely sure to end this war of independence within two years.

But this was not the result that Stone Bear wanted to see, so he took the initiative to blockade the Chesapeake Bay, and ordered his intelligence chief Rabbit Mouth to begin secretly assisting the Continental Army, and even sent elite scouts from the Grim Bear Army to help the Continental Army. Fight guerrilla warfare.

　　 It was after this multi-pronged approach that the Southern Continental Army relied on the covert support of the Yanhuang tribe and the fighting style of guerrilla warfare to reverse the unfavorable situation on the southern battlefield.

　　 Although still unable to defeat the British, it has been able to contain the main force of the British army very well.

　　 Therefore, the main forces of the United Kingdom and the United States are entangled in the northern battlefield. The situation in the northern battlefield has always been under a delicate balance of brilliant canine teeth. The British army has the upper hand, but it is unable to win the main force of the Continental Army.

　　 So, the key node of this war appeared on the southern battlefield.

　　Whether the British army or the Southern Continental Army in the southern battlefield can win on the southern battlefield can directly determine the outcome of the northern battlefield and even the entire War of Independence.

　　 But by the way, on the southern battlefield, the two sides were also inextricably fought, and no one dared to say that they would win.

In the original historical time and space, the combat value of the southern battlefield lasted for two years. It was because the British army encountered a series of inexplicable failures and the outbreak of the plague, which eventually led to the occurrence of the Great Victory of Yorktown, and Cornwallis led the South. The army surrendered to the Continental Army in Yorktown, leading to the end of the entire War of Independence.

　　 But in this time and space, because of the participation of Shixiong, the southern battlefield, which should have been over for two years, has now been played for a full four years without a victory or defeat.

　　Even the British barracks encountered the plague, but they were treated very well with the assistance of the Yanhuang tribe.

　　 When he was developing penicillin, Jean Agusti started to purify quinine under the guidance of Shixiong.

　　 Quinine is cinchona frost. This thing is native to Peru, but there are also a lot of cinchona trees in the southern part of the North American continent at this time.

　　 At first, Shixiong wanted AgustaWest to directly purify artemisinin, but he couldn't find Artemisia annua that could be used to purify artemisinin.

　　 Yes, Artemisia annua, as defined in later modern botany, actually cannot produce artemisinin. Artemisinin is extracted from a plant called Artemisia annua. If such an error occurs, the kid should be blamed for everything.

　　 In the Compendium of Materia Medica by Mr. Li Shizhen that year, it was clearly pointed out that "Artemisia annua" and "Artemisia annua" are synonymous, and both are Artemisia annua. At that time, Xiao Guizi’s scholars highly praised the Compendium of Materia Medica, but they couldn’t tell the difference between the true Artemisia annua and Artemisia annua. So Xiao Guizi’s scholar Zhang Guanli Dai gave the name Artemisia annua to another species that does not produce green. Artemisinin plant-Artemisia annua.

　　 Artemisia annua was only produced in the temperate zone of Eurasia, but there is no such plant in North America. Although colonists also brought this plant to the North American continent in this era, Artemisia annua has not been promoted in the North American continent. After all, in the eyes of the colonists, this kind of plant that can be seen everywhere on the roadside is a kind of weed.

　　 Without Artemisia annua, artemisinin cannot be extracted naturally. So Shixiong retreated and asked Agustadays to refine quinine.

　　 Although quinine has been around for more than a hundred years, due to the shortage of raw materials, this good medicine for falciparum malaria simply cannot be popularized on a large scale.

　　 However, there are many cinchona trees in the territory controlled by Stone Bear, so he naturally has enough raw materials to refine quinine.

　　 Shixiong has prepared a lot of quinine for a long time, in order to help the British alleviate the loss of people caused by the malaria outbreak.

　　 It was with Shixiong’s secret help that the British did not lose too many soldiers during the malaria outbreak.

　　Stone Bear helps both sides, so that both sides can leave more power to fight...

　　 In this way, the war in the southern battlefield has lasted for four years. If it continues like this, the ghost knows when the southern battlefield can end the battle~lightnovelpub.net~ This is of course something Shixiong is happy to see. The Yanhuang tribe only quietly gave some insignificant things, so that the brains of the British and the Americans became dog-headed, and the two sides became weaker and weaker under the constant bleeding of each other.

　　 But it was a pity that Shi Xiong felt that this kind of smashing each other's eyes and stabbing each other with a knife only lasted for four years before it had to end.

　　The reason is not in the North American battlefield, but in another battlefield on the other side of the Atlantic Ocean-the Fortress of Gibraltar.

In the original historical time and space, Spain declared war on Britain on June 16, 1779, and then with the support of the French, it dispatched 35,000 soldiers, 47 warships, and more than 100 doors. The type of heavy artillery besieged Gibraltar, which was guarded by only 7,300 British troops, for three years and seven months.

　　 It is precisely because of this offensive and defensive battle that most of the energy of the British navy's main fleet has been held back, leading to the further deterioration of the situation in North America.

　　 The Atlantic Ocean is too big, and the main British naval fleet cannot take care of the battles on both sides of the ocean in a short period of time.

　　In the original historical time and space, when the British saw that the situation in North America had been so corrupted that it was irreversible, they decided to abandon the thirteen colonies in North America and instead focused on Gibraltar. Since North America cannot be kept, then keep Gibraltar!

　　 In this time and space, the deterioration of the offensive and defensive battle of the Gibraltar Fortress also made the British have to make a choice...
